Uranium series dating labs

They use a tricky method we will explain in a moment. No matter what the starting point, it always ends up at the same end point. The highest ratio sample O was more than , times what the Old Earth model predicts.

Uranium Daughter Laboratory. Using the 230 Th/U and 234 U/ 238 U methods, this lab is capable of dating samples ranging in age from about a million years old to less.

Uranium series chronology of speleothems not only provides useful constraints on speleogenetic processes, but forms the backbone of the increasingly important scientific field using stalagmites and less commonly flowstone as paleoenvironmental archives.

Back to their method of dating the paintings: Is that assumption reasonable?

How Old is that Rock?

A recent article about U-series dating of Paleolithic art in 11 caves in Spain 1 contained some frank discussions about the wild assumptions that had to be made to date the paintings, and raised some interesting questions about the scientifically accepted age of the Earth.

Note that to calculate an age using this technique the ratio of uranium to its parent isotope uranium must also be measured.

Uranium-series dating has recently been applied to figures on the decorated ceiling in the cave. The value of Y changes very little with TIME.
